Iris, the Grand Dame of Ospreys

As the days of summer give way to thoughts of falling leaves and back to school, our beautiful Ospreys think of migration. Those in the United Kingdom have already already headed to the area around Poole Harbour to have a last good feed and sleep on land before heading south to Brittany and on to Africa. Those in the United States and Canada will take various routes. The male is still in Manitoba with one chick at the nest I watch.Some head to southern Texas and places in Mexico while those in the northeast fly over the cost, over the length of Cuba heading to South America. One of those leaving her summer breeding grounds in Missoula, Montana will be Iris.

Iris is not ringed. No one knows where she goes for the winter but, she turns up in tip top shape to her nest at Hellgate Canyon every spring.

Typically Iris spends more time at her nest before her departure. Last year she said goodbye on 8 September. Because of her age, many worry that she will not return. It is always an anxious wait until spring and she arrives again full of hope and hormones.

Sharon Leigh Miles shared this image of Iris taken on her favourite tree on Mt Sentinel on 6 September at 09:22.

She is there. Just squint.

Iris is the oldest osprey in the world – the grand dame of all of them. In her lifetime it is estimated that she has fledged between 30 and 40 chicks but no one knows for sure. It is possibly more. Iris is known around the world. Her arrival on 7 April 2021 to her Hellsgate nest made print and television news. Dr Ericke Green of the University of Montana believes Iris is at least 25 years old, perhaps more.

In the image below, Iris just landing from her winter migration. All the worrying about whether or not she survived another winter is put to rest.

Welcome home, Iris. 7 April 2021
Landing with a nice big breakfast. 10:36 am. 11 April 2021

Iris’s nest, prior to the one she uses now, was on a hydro pole about 68 metres or 200 feet from this one. This artificial nest was built for Iris because of the high rate of electrocutions on power lines – all birds, not just Osprey. The power lines are high enough and have a clear view that they appear to be desirable. The new nest, erected in 2007, is all set up with a high resolution camera. Iris took to the new nest right away, thankfully. Iris mate, at the time was Stanley. Stanley did not return from migration in 2016. Her current mate, Louis, and her have had a very chequered relationship. Louis also has another nest with Star, his primary nest, near the baseball park. Iris and Louis fledged one chick, Le Le, in 2018.

Many of us are glad that Iris has been spending the summer of 2021 taking care of herself. Raising chicks is not an easy job – and everyone loves Iris and wants her to return year in and year out from her migration.

I have included some images taken at the nest this year.

Iris worked on building the best nest that she could. Every day she brought in more material. She eventually will lay three eggs – that we and she – seem to know are destined not to hatch. These were bittersweet moments for everyone.

She was fierce in her fishing and the protecting of her nest. Indeed, her and Louis protected the nest together several times. The video below is from 22 August.

Sharon Leigh Miles provided a chart of the departure dates for Iris for her migration. Today is 6 September so we are definitely in the range. These are the previous dates of her departure:

  • 2012: 6 September
  • 2013: 6 September
  • 2014: 11 September
  • 2015: 4 September
  • 2016: 8 September
  • 2017: 9 September
  • 2018: 10 September
  • 2019: ?
  • 2020: 8 September

There is no one on the Hellgate Canyon nest this morning. Everyone is hoping that Iris will make several long appearances on the nest before she departs. This has been her MOD in the past. Fingers crossed!

If you would like to periodically check on the nest, here is the link to the streaming cam:

The Montana Osprey Project has had one fundraiser – the Iris pens – this year. If you would like information on how to order one of these, send me an e-mail and I will provide the details. They are lovely. There are also plans to commemorate Iris by a woodblock print. As information comes through I will post it.

Keep Iris in your heart. Migration is challenging. We wish her a safe journey, good winds, lots of fish, and a safe return to Montana in the spring.

Thanks for joining me. Take care everyone.

Sadness on Channel Islands Bald Eagle nest and other news from Bird World

There is sad news coming out of the Channel Islands Bald Eagle community. The male eagle, A64, Spirit, devoted mate to Cruz, was found floating in the ocean near Fraser Point on 21 July. The report stated that there appeared to be no traumatic injuries. Spirit’s mate, Cruz, has been seen at their nest. Condolences to all.

Deb Stecyk made a great video of this wonderful couple in 2018. Here it is:

The gusts have really been whipping the Fortis Alberta Exshaw Nest around this afternoon. For awhile it looked like the two chicks might get blown off. Mum was food calling and looking in the sky and you sure had a lot of sympathy for dad trying to fish and feed his family this afternoon. The weather station reports that the winds are blowing at 21 km/h. The gusts appear to be more than that. Hang on everyone!

Of course, you can’t even tell there is a breeze in a still photo!

The chicks are doing well on this nest. There seem to be no worries.

The wind was not blowing at the Fortis Alberta Red Deer Osprey Nest. Just look at how big and pretty Only Bob is getting! It really does help to be an only chick.

As the day heats up, Mum is making sure that this little one is good and shaded from the pounding heat of the sun.

The Only surviving Bob at the Collins Marsh Nest had a nice crop this morning. It is really, really hot on the top of that old wildfire tower. Both Mum and chick are really panting.

It was really nice to see a nice big crop on this little one today especially with the heat.

Tiny Little had breakfast and had an evening meal. Mom flew in to help but looks like Tiny Little did a pretty good job cleaning up. Our little one decided to sleep duckling style on the nest tonight. I like to think that all those lines are golden rays shining down and protecting this wee babe.

Other news coming out of Welsh Osprey nests is from Llyn Clywedog, the nest of Dylan and Seren. Only Bob, Blue 496, today flew from the nest with a good sized fish attached to its talons to eat it elsewhere. It is not clear if this is a first for Only Bob but it sure could be. Well done! Another milestone.

This is so fantastic. Dylan and Seren can be very proud of their 2021 fledgling Blue 396. He is doing so well in all aspects – flying, self-feeding, and now flying with a fish in talon. All good prep for migration.

As you probably know, the mothers leave before the fledglings and dad. They normally take off for Africa (or Spain or Portugal) two weeks before everyone else. Seren has been photographed in The Gambia. Dad will stay behind and feed the fledglings. When they take off and are all on their way it is only then that the male will leave. Everyone knows what a treacherous undertaking migration is. This year only 80% of the Ospreys expected to return did so in the UK (according to Tiger Mozone’s data). That is low. Normally it is 90%. We will begin to look for their return the third week in March. Normally Blue 33 and Maya are one of the first couples to get back to their nests. I can’t wait. There is something adorable about these little fuzzy bobble heads turning into reptiles and then getting their juvenile plumage that warms your soul.

My last report comes from Dr Ericke Green at the Montana Osprey Project. Him and his team have now visited 200 Osprey nests along the Clark Fork River. They note that the water in places is less than half the normal amount. The heat has persisted for more than a month, the water is hot, and the fish are dying. This is bad news for the Ospreys. Green noted that the chicks that they ringed were in good shape, regardless. He said that when they were on the Flathead Indian Reserve north of Missoula they found some nice healthy chicks living in nests lined with Bison hair! The nest is close to the Bison Wildlife Refuge. Wouldn’t that be soft and cosy?

Do any of you know what has happened in the Barlinecka Forest’s Osprey Nest in Poland? I have written to the Polish Committee for the Protection of Eagles that ran the camera. It has gone off line. There were two chicks on the nest – chick 1 hatched on 25 May and chick 4 hatched 31 May. Eggs 2 and 3 did not hatch. That is a massive difference in age! If you know anything about the status of these birds please let me know. I haven’t had a response yet from Poland. I will share it if I hear.

I want to thank all of you for joining me today. It is always a pleasure to have you with me. It was helpful to hear Dr Green say that this year’s osprey chicks in Montana have done well despite the drought that is encompassing so much of that area and ours in Canada. Take care everyone. Tomorrow loads of images of Big Red and the Ks.
